gt35r install over the weekend
I took advantage of this long weekend to get my ATP gt35r turbo kit installed along with my ProSport EGT gauge. Very few things went smoothly to say the least...
Ok, so about a month ago I bought the kit with 1000 miles from the for sale section. It had some missing pieces, but I was able to get everything I needed...or so I thought.
Here are the things I needed to get or modify to get the kit to fit.
4 grade 10.9 m10 1.5 pitch bolts from ace hardware to bolt the turbo housing to the stock exhaust manifold. These bolts come with the kit, but I was missing them.
The wastegate pipe that connects to the downpipe was a bit of a pain to get on. Everything on the downpipe needed to go in an exact sequence. First the bare downpipe had to go on. Then the v-band loosely slipped over. Then carefully connect the wastegate pipe while pushing the downpipe downwards with the vband still partially on.
The downpipe does not fit right at all to the catback. Currently the downpipe is pushed up against my ACD transfer case. The kit is advertised to fit the evo 9, but the downpipe is clearly not made to fit with the ACD.
4" to 3" silicone coupler connect a pipe to the stock airbox
various t-bolts and worm clamps
had to build a 3" intake pipe to connect to the stock air box using some 3" bends cut and welded together
the lower intercooler pipes that came with the kit ended up being about 4" short. Had to cut a 4" section of 2.5" pipe to bridge the gap. I also welded a bung on this pipe for the waste gate boost line.
Besides running into those issues, the kit fit OK and my car is driveable. My only concern is the downpipe against the transfercase.
Right now I am boosting only 10psi since I put a 10psi spring in the wastegate since I am a paranoid. Feels like Its making a bit less power (20-30hp) then the stock 9 turbo @ 20psi. I still have 880cc injectors and a walbro to put on before I start cranking the boost.
I think I have everything else taken care of on the car to be making 400awhp on 93 octane. My goal is to just have a 400hp daily driver. I have a stage 2 transfer case, 6 pluck ACT clutch, AMS front mount. I don't ever plan on opening the engine at all (even for cams) or running any kind of gas (meth). Been tuning already with EcuFlash and logging with an AEM wideband logging with EvoScan.
On with the pix that were taken over the weekend.

I am planning to modifying the exhaust within the next month
edit: the only part that is touching the transfer case is the vband. I think if the vbands were chopped off and 2 pipe sections welded together it would fit OK.

haha... Looks like you had fun Dan.
Theres another ATP 35R kit that just surfaced in the FS section I was looking at.
I told you ATP's stuff fit shoddy

I have a atp 30r (thinking of upgrading already and I just got it) and it touchs the case a little also and when you hit bumps I can hear it tapping on there....also a bolt on the tranny was almost touching/in the way after it was installed...it was a really tight fit for my xs intake. I will address that big vband clamp issue real soon...probably cut the pipe and relocate the clamp acouple inches back.

After work today I took the downpipe off and busted out the mig welder to join the downpipe to get rid of the middle v-band. The downpipe fits ALOT better now and it has about 3mm of clearance between the transfer case which is within my comfort zone. I could always lob off another 2-3mm if i hear it hitting the tcase.
I think GG_9_SE is 100% correct about the downpipe "rubbing through". I only drove 80 miles and the transfer case has a nice scar on it. Dont risk running a downpipe that is pressed against the transfer case!!!!
Ill be keeping the stock airbox for now.

Hard to tell from running a crappy 10psi spring. The boost hits 8psi then creeps SLOWLY to 10psi. Seems the boost comes on about 700rpm later then the stock 9 turbo. Need to get avcr on this thing to get it to really peg.
